CMS Targets Medicaid Fraud in 2026

HHS announced that Vice President J.D. Vance, HHS Secretary Robert F. Kennedy, Jr., and CMS Administrator Dr. Mehmet Oz unveiled new steps to crack down on Medicare and Medicaid fraud at a White House event. CMS simultaneously released a press statement describing a “major crackdown,” including a $259.5 million federal Medicaid funding deferral for Minnesota (as characterized in CMS materials). CMS framed the effort as protecting patients and taxpayers.

CRUSH RFI Signals Potential Program Integrity Changes

To operationalize the broader initiative, CMS published an RFI in the Federal Register titled “Request for Information (RFI) Related to Comprehensive Regulations To Uncover Suspicious Healthcare (CRUSH).” The agency is seeking stakeholder feedback on potential regulatory and programmatic changes intended to “crush fraud.” Comments are required by March 30, 2026.

Within the RFI, the Medicaid and CHIP section focuses on preventing fraud in service areas identified as “high risk” in certain states. CMS explicitly lists the following categories:

• Housing stabilization services

• Behavioral health services

• Personal care assistant (PCA) services

• Nonemergency medical transportation

The RFI also solicits ideas on technology and AI-enabled practices, pointing to a potential expansion of tools used for oversight and detection.

Minnesota Funding Deferral Highlights Immediate Financial Stakes

In the immediate aftermath of CMS’s announced actions, Minnesota filed litigation seeking to block federal withholding of Medicaid funds. The legal response underscores that the program integrity push is not limited to compliance theory. It can translate quickly into cash-flow risk, public dispute, and operational uncertainty for states and providers. CMS materials characterize the action involving Minnesota as a federal Medicaid funding deferral totaling $259.5 million, reinforcing the scale of the enforcement posture described in the agency’s press statement.

What IDD Providers Should Watch In 2026

For IDD providers, the RFI’s explicit naming of PCA services and nonemergency medical transportation is a strong signal that staffing models and support logistics common in Home and Community-Based Services (HCBS) may face heightened scrutiny. Even if enforcement initially targets outlier bad-actor behavior, broad crackdowns often produce more defensive payer behavior. That can include more prior authorizations, post-payment reviews, increased documentation demands, added electronic visit verification (EVV) rigor, and a narrower tolerance for billing anomalies.

The RFI’s focus on “cutting-edge technological tools” and integrating AI into oversight also suggests that Medicaid program integrity could shift toward more real-time anomaly detection and predictive analytics. For providers, that direction may increase audit velocity and reduce the time available to correct errors before denials or recoupments occur.
